Basically it is a SQL database specifically enginnered for building big datawarehouses. Uses parrallel processing for everything. It can scale in all dimensions almost infinitely. Can run on Unix and Windows servers.

It uses architecture of independent and self-sufficient nodes. Performance grows linearly with the number of added nodes (processors, servers). Performance does not deteriorate with increasing numbers of simultaneously working users.

Unlimited parallelism between nodes / servers leads to unlimited efficiency (time to get 100 rows can be the same as to get million rows).

Up to 64 joins in a query.

Data Types:
